This part number is commonly listed as superseding 91160810200 and cross-references Bosch 0580254984 (reference numbers for comparison).
This OE Match fuel pump is designed to deliver a steady, pressurised fuel supply from the tank to the engine’s injection system, supporting stable combustion and consistent performance. Manufactured to match the factory form and function, it’s built to the correct flow/pressure characteristics and includes a one-way valve to reduce hot-start issues and improve pressure retention in the fuel lines.
The pump draws fuel from the tank and sends it forward under controlled pressure to the engine’s fuel delivery system. The integrated check valve helps keep fuel from draining back, supporting faster restarts and more stable system pressure.
A weak or failing fuel pump can cause hard starting, hesitation, poor acceleration, lean running, or intermittent cut-out. Replacing it with an OE Match pump restores correct fuel pressure and consistent delivery - critical for performance and engine protection.
When to replace:
• Extended cranking / hard starting, especially hot starts
• Whining/noisy pump or inconsistent fuel delivery
• Hesitation or loss of power under load
• Fuel pressure tests show low or unstable pressure
• During fuel system refresh on higher-mileage cars

High Pressure
Fuel Pump Tappet
Sold each - 2 required per car
The high pressure fuel pump tappet is a
precision-engineered component used in the direct-injection fuel system of Porsche
976 Panamera 4.0-litre models and 9YA.2 Cayenne 4.0-litre models.
Positioned between the camshaft and the high-pressure fuel pump, this tappet
transfers camshaft motion to drive the pump and generate the fuel pressure
required for efficient combustion.

Diagram ref no 13
In high-output Porsche V8 engines, accurate fuel pressure delivery is essential for performance, emissions control and long-term engine reliability—making this tappet a critical service part.
What Does a High Pressure Fuel Pump Tappet Do?
The tappet converts the rotating motion of the camshaft into
linear movement that actuates the high-pressure fuel pump. This process allows
the fuel system to:
Maintain
precise high fuel pressure
- Support direct fuel injection under load
- Ensure stable engine performance across the rev range
- Optimise combustion efficiency and emissions
Without a properly functioning tappet, the fuel pump cannot operate correctly, leading to drivability and performance issues.
Why Do High Pressure Fuel Pump Tappets Fail?
Due to their location and function, fuel pump tappets are
exposed to continuous mechanical contact, high loads and insufficient
lubrication risk. Common causes of failure include:
- Surface wear from camshaft contact
- Breakdown of protective coatings
- Oil contamination or reduced oil flow
- Extended service intervals
Typical symptoms of tappet wear or failure include:
- Loss of engine performance
- Fuel pressure fault codes
- Rough running or hesitation
- Increased wear to the camshaft or fuel pump
Why Replace the Fuel Pump Tappet?
Replacing a worn tappet helps:
- Restore correct fuel pressure delivery
- Protect the camshaft and fuel pump from damage
- Maintain smooth, consistent engine performance
- Prevent costly fuel system or valvetrain repairs
Early replacement is particularly important on high-performance 4.0-litre Porsche engines where component wear can escalate quickly if ignored.6

This updated OE part replaces multiple earlier fuel pump versions: 9A791908810 9A791908811 9A791908812 9A7919088A.
These older numbers have been consolidated into PAE919088A, ensuring improved compatibility and updated design.
The fuel pump draws fuel from the tank and delivers it to the engine’s high-pressure fuel system, maintaining a constant supply required for combustion. It ensures stable fuel pressure under all driving conditions, from cold start to high load.
In modern Panamera engines, the in-tank pump works together with the engine-mounted high-pressure pump to support direct fuel injection systems and optimise performance and efficiency.
Functions & Technical Role
• Fuel delivery: Supplies fuel from the tank to the engine
• Pressure stability: Maintains consistent low-pressure feed to the high-pressure system
• Integrated module: Combines pump, sender, and strainer in one assembly
• Engine performance: Supports smooth running, acceleration, and efficiency
• OEM precision: Designed to Porsche specifications for correct fit and operation
Fuel pumps operate continuously under demanding conditions. Over time, wear or failure can lead to:
• Hard starting or no start
• Loss of power or hesitation
• Engine stalling Fuel system warning faults
Replacing with a genuine Porsche OE fuel pump restores proper fuel pressure, reliability, and engine performance.

This OE Match Fuel Pump is a high-quality replacement component engineered to meet original Porsche standards for fit, performance, and durability. Installed inside the fuel tank, this electric pump forms a critical part of the fuel delivery system, ensuring a steady and reliable flow of fuel to the engine.
This unit functions as a fuel pump and sender assembly, drawing fuel from the tank and delivering it through the low-pressure system to support efficient engine operation. Designed specifically for modern Porsche Panamera platforms, it ensures consistent fuel supply under varying driving conditions, from everyday use to high-performance demands.
Manufactured from durable, fuel-resistant materials, the pump is built to withstand continuous operation, temperature fluctuations, and fuel system pressures. It is a direct replacement for multiple superseded part numbers, including 9A791908810, 9A791908811, 9A791908812, and 9A7919088A, ensuring broad compatibility across applicable vehicles.
This fuel pump is typically specified for non E-Hybrid models (PR code dependent) and is supplied as a complete in-tank assembly, making installation straightforward and reliable.
Function
• Pumps fuel from tank to engine fuel system
• Maintains stable fuel pressure and flow
• Supports efficient combustion and engine performance
• Integrates fuel level sending functionality (depending on model)
• Ensures reliable operation under all driving conditions
A failing fuel pump can cause inconsistent fuel delivery, leading to poor engine performance, hesitation, or starting issues. In modern direct injection engines, maintaining a stable fuel supply is essential for efficiency and reliability.
Replacing the fuel pump restores proper fuel system operation, improves drivability, and helps prevent further strain on injectors and other fuel system components.
When to replace:
• Engine struggles to start or fails to start
• Noticeable loss of power or hesitation
• Engine stalling or irregular fuel delivery
• Audible fuel pump noise from tank
• Fault codes related to fuel supply system
